Abstract

FIELD: apparatuses for receiving, transporting and uncoiling coils of rolled strip fed successively from rolling mill or storage.

SUBSTANCE: apparatus includes turntable-type holder driven to rotation around vertical axis and supporting pair of carrying mandrels mutually shifted by 90° spaced along radius and mounted with possibility of rotation. Said mandrels have axial locking members. Turntable type holder rotates mandrels by 180° from position for receiving coils of rolled band to position for their uncoiling. Holder also includes two additional carrying mandrels shifted relative to main mandrels by 90°. Between positions for receiving and uncoiling and also between position for receiving carrying mandrels and uncoiling position there are additional working positions for removing binding tape from coil, placing it on coil and marking coil.

EFFECT: enlarged functional possibilities, namely possibilities for performing not only operations for receiving, rotating, uncoiling and removing coils but also operations for inspecting coils, placing binding tape or removing it, marking, weighing coil and so on.

Description

The invention relates to a device for receiving, further transporting and unwinding rolls of rolled wire, fed one after another from a rolling mill or warehouse of rolled wire, consisting of a rotary holder rotatable around a vertical axis with four radially offset 90 ° relative to each other spaced, rotatably mounted supporting mandrels with axial locking elements, which rotates them from the position of receiving riots of rolled tape by a certain angle of rotation in pos The removal or unwinding function.

Devices are already known by means of which the rolled strip supplied from the rolling mill is wound onto a supporting mandrel mounted on a carousel holder, driven into rotation by a carousel holder, moved to a different position by means of a carousel holder, and the rolled bundle is unwound again in this position (EP-A-0576890 and FR-A-1158457). According to another proposal, on a pair of carousel holders located at a distance from each other, there are four bearing mandrels spaced 90 ° apart from each other, and scissors for longitudinal cutting into strips are provided between the two carousel holders. The device serves to put rolls of rolled tape on the supporting mandrels of one carousel holder one after another, feed the tape with unwinding to scissors for longitudinal cutting into strips, feed the resulting bands to the supporting mandrel of another carousel holder and wrap it (US- A-2202883). Further, the proposal is known, according to which in the strip mill between two sequences of rolling stands there is a carousel holder that carries two pairs of coilers rotationally displaced relative to each other. The device serves to wind the rolled tape from the same sequence of rolling stands of the rolling mill in the first pair of coilers and, if necessary, process it, then feed it to the second pair of coilers for further processing and transfer it from it to another sequence of rolling stands (DE -C-972603). According to another proposal, the supporting mandrels located on the carousel holder are used so that the rolls of rolled tape supplied by the means of internal workshop transport or on the lifting beam and brought to the horizontal average axial position are mounted on one of the supporting mandrels, axially fixed on it, rotated the supporting mandrel with the rolled tape to the unwinding position, and then unwind the riot of the rolled tape, and at this time the next roll of the rolled tape can be worn on another, located at the receiving position pinched the mandrel and is fixed on it (US-A-3870244).

The basis of the invention is the task of improving this device so that, with its help, the riots of rolled tape coming from a strip mill or drive can not only be received, turned, unwound and removed again, but also in conjunction with such turning movements, to carry out other actions with the feed and with a retractable riot of rolled-up tape, such as, for example, inspection of a riot, placement of a strapping tape or its removal, marking a riot, weighing a riot, still known on the preparatory winder and so on

This problem is solved due to the fact that the carousel holder has at least two positions shifted 90 ° between the receiving position and the unwinding position with devices for removing the strapping tape, marking the riot and tying the riot. Moreover, as further contemplated by the invention, in the area of the unwinding position, a motionless rotation drive may be provided, connected by rotation with a correspondingly opposite carrier mandrel. Further, in the area of this unwinding position, tape scissors can be installed on the trajectory of the uncoiled tape riot. Behind the tape scissors, a straightening device can be located. This embodiment of the device according to the invention requires significantly less space and lower costs for foundations, and, in addition, there is no longer any need for the intermediate transportation of rolled-up strip riots that has been required so far, as well as the receiving and transport devices necessary for this.

The invention is explained in more detail using the example shown in the drawing.

As can be seen from the drawing, four rotary mandrels TDI, TDII, TDIII, TDIV are located on the carousel holder KT mounted rotatably around the vertical axis VA with a 90 ° offset relative to each other. They are not shown in the drawing, they are installed in the rotary holder CT with the possibility of rotation around their longitudinal axes. Each carrier mandrel TD comprises a locking device RV for axially securing the rolled-up strip ripped on the mandrel. With the rotation of the CT rotary holder in the direction of arrow S, the carrier mandrels can be rotated one after another, starting from position A, each time rotated 90 ° to positions B, C and D. At position C, it is axially opposed to the rotated carrier mandrel, here TDIII, in a fixed housing AG the drive with the ability to move or rotate in the axial direction is the docking device KV.

The device operates as follows. The carrier mandrel I, which is located at position A, is put on, for example, from a rolling mill or a rolled-up tape storage device, brought in by lifting beams or other transport devices, indicated here by the dotted line riot WB of the rolled-up tape, axially fixed by an RV blocking device and subjected to processing, for example, inspection. Then, the carousel holder CT rotates around the vertical axis VA by 90 ° in the direction of arrow S and brings the rip WB of the rolled tape to position B. At this position, the reel WB of the rolled tape can be further processed, for example, a strapping tape can be removed. The following rotation movement of the rotary holder KT by 90 ° rotates the rip WB of the rolled tape to position C. At this position, the supporting mandrel I is joined with it by moving the docking device KV in the double arrow P and, thereby, it is possible to unwind the tape BD marked with a dash dot from the riot , if necessary, separation of the beginning of the tape BD using scissors BS located in the direction of unwinding behind the riot of the rolled tape. The rebellion WB of the rolled tape remaining on the supporting mandrel I at the end of the separation process, due to the next rotation movement of the rotary holder CT again by 90 ° is moved to position D and after additional processing, i.e. strapping tape placement, marking, etc., are removed from the TDI carrier mandrel and fed for further processing. At the end of these processing steps, already during the first further processing of the rolled strip WB roll WB to position E, the next rolled roll WB roll can be put on the next free carrier TDII, which is now at position A, and then with the next turning movement of this carrier TDII to the position B, put the rolled-up strip WB next onto the free supporting mandrel TDIII, turned to position A, etc. Riots WB riots can thus be subjected to four different treatments simultaneously in a single time span.
